Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Nashville Metro, TN (KBNA), launched 00:00Z, 11.1 hours before the alert went out and 171 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Jackson, KY wrote its last area forecast discussion before this severe thunderstorm warning went out at May 22, 3:45 AM EDT, 3 hours 20 minutes earlier.

Area forecast discussion, May 22, 3:45 AM EDT, 3 hours 20 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
345 AM EDT THU MAY 22 2014

.SHORT TERM...(TODAY THROUGH FRIDAY)
ISSUED AT 345 AM EDT THU MAY 22 2014

MODELS HAVE BEEN HAVING A DIFFICULT TIME RESOLVING THE CLUSTERS OF
THUNDERSTORMS THAT HAVE BEEN PLAGUING THE AREA SINCE LATE WEDNESDAY
EVENING. THE FORECAST FROM 6Z THROUGH NOW WERE UPDATED MOSTLY USING
THE LATEST TRENDS OBSERVED IN RADAR AND SATELLITE IMAGERY. CURRENT
ACTIVITY HAS BEEN SHOWING A STEADY WEAKENING TREND OVER THE PAST HOUR
OR SO. ALL INDICATIONS ARE THAT ANY REMAINING THUNDERSTORMS WILL
PRODUCE MINIMAL WIND GUSTS AND ISOLATED INSTANCES OF LOCALLY HEAVY
RAINFALL THROUGH THE REMAINDER OF THE OVERNIGHT. MORE STORMS CONTINUE
TO FORM IN A PREFERRED AREA OF LIFT AND MOISTURE CONVERGENCE ACROSS
SOUTHERN INDIANA AND WILL LIKELY CONTINUE TO MOVE ACROSS CENTRAL AND
EASTERN KENTUCKY THROUGH EARLY THIS MORNING. THE MODELS ARE
INDICATING THAT THERE WILL BE BRIEF LULL IN ACTIVITY IN THE
MORNING...BEFORE THINGS RAMP BACK UP A BIT DURING THE AFTERNOON HOURS
AS A COLD FRONT SAGS SLOWLY SOUTHWARD ACROSS THE REGION OUT OF THE
OHIO VALLEY. THE MODEL CONSENSUS SAYS THAT THE LAST SHOWERS AND
STORMS WILL BE OUT OF THE AREA AROUND 5Z FRIDAY. THERE IS A SLIGHT
RISK THAT A FEW STORMS COULD APPROACH SEVERE LIMITS ALONG AND JUST
NORTH OF THE TENNESSEE BORDER TODAY...AS THIS WAS MENTIONED IN THE
HAZARDOUS WEATHER OUTLOOK EVEN THOUGH CONFIDENCE IS NOT HIGH THAT
THIS WILL OCCUR. STRONG WINDS AND LARGE HAIL WOULD BE THE PRIMARY
THREATS WITH ANY STORMS THAT REACH SEVERE STATUS. THE WEATHER FOR
THURSDAY NIGHT AND FRIDAY WILL DRY AND SLIGHTLY COOLER AS ANOTHER
RIDGE OF HIGH PRESSURE SETTLES OVER THE AREA.

TEMPERATURES TODAY WILL BE RUNNING ABOVE NORMAL ONCE AGAIN WITH
READINGS EXPECTED TO TOP OUT AROUND 80 DEGREES ACROSS THE AREA AS THE
AIR MASS BEHIND THE COLD FRONT QUICKLY MODIFIES. THE FRONT ITSELF IS
NOT ALL THAT WELL DEFINED SO THE AIR BEHIND IT WILL PROBABLY NOT COOL
THINGS OFF VERY MUCH ONCE THE FRONT HAS PASSED. INSPITE OF THE
SLIGHTLY COOLER AIR MASS...TEMPERATURES ON FRIDAY SHOULD STILL BE
ABLE TO TOP OUT IN THE UPPER 70S ACROSS THE BOARD.

.LONG TERM...(FRIDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 330 AM EDT THU MAY 22 2014

THE MODELS IN THE LONG TERM START OUT IN VERY GOOD AGREEMENT WITH A
CUT OFF UPPER LOW OVER ARIZONA...UPPER RIDGING OVER THE PLAINS AND
AN UPPER TROUGH OVER THE EAST COAST. AT THE SURFACE HIGH PRESSURE IS
DOMINATING THE AREA. THE UPPER LOW OVER ARIZONA TRACKS SLOWLY TO THE
NORTHEAST OVER TIME AS THE RIDGE AXIS MOVE SLOWLY TO THE EAST AND
WILL BE LOCATED OVER THE MISSISSIPPI VALLEY BY SATURDAY EVENING. BY
TUESDAY AFTERNOON...SOME AFTERNOON AIR MASS THUNDERSTORMS MAY BE
POSSIBLE AS THE UPPER LOW APPROACHES THE AREA. BY THIS TIME THE
MODELS ARE STARTING TO DIVERGE AND CONFIDENCE PLUMMETS. ISOLATED TO
SCATTERED THUNDERSTORMS WILL BE POSSIBLE THROUGH THE END OF THE
PERIOD. FOR TEMPERATURES...STAYED CLOSE TO THE MODEL BLEND...HOWEVER
NUDGED THEM TOWARD THE RAW ECMWF AND MADE CORRECTIONS DUE TO
TERRAIN.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z THURSDAY EVENING)
ISSUED AT 810 PM EDT WED MAY 21 2014

CONDITIONS ARE CLINGING TO VFR THROUGH THE AREA...BUT THE CIGS DO
REMAIN NEAR MVFR IN THIS HUMID PRE-STORM ENVIRONMENT. CONVECTION...
STRONG TO SEVERE...IS ON TRACK TO PUSH SOUTH INTO THE FORECAST AREA
OVER THE NEXT SEVERAL HOURS. HAVE FORECASTED THE WORST CONDITIONS FOR
THE WESTERN PORTION OF THE AREA...LOZ AND SME. WHILE TO THE EAST...AT
JKL AND SJS...HAVE KEPT IT A BIT TAMER. EXPECT THE THREAT OF
THUNDERSTORMS AND LOWER CIGS TO LINGER THROUGH THE REMAINDER OF THE
AREA INTO THE MORNING THURSDAY...AND EARLY AFTERNOON TO THE SOUTHWEST.
HOWEVER... CONDITIONS WILL IMPROVE FROM NORTHEAST TO SOUTHWEST AS A
COLD FRONT RETREATS TO THE SOUTHWEST WITH TIME. KEPT THE RISK OF
THUNDER AND THE LOWER CIGS IN FOR SME THE LONGEST. WINDS WILL BE
OCCASIONALLY BREEZY FROM THE WEST SOUTHWEST THROUGH THE EVENING...BUT
WITH STORMS THE GUSTS COULD BE UP TO 40 KTS OR HIGHER IN THE
WEST...THOUGH CLOSER TO 30 KTS IN THE EAST. LIGHTER WEST WINDS...
OUTSIDE OF ANY STORMS...WILL FOLLOW FOR THE REST OF THE NIGHT AND
INTO THE DAY THURSDAY.
